In Vietnam, although female sex workers carry a disproportionate burden of HIV, little is known about the risk profile and associated factors for HIV infection among this population. There is a need for large-scale research to obtain reliable and representative estimates of the measures of association. This study involved secondary data analysis of the 'HIV/STI Integrated Biological and Behavioral Surveillance' study in Vietnam in 2009-2010 to examine the correlates of HIV among female sex workers. Data collected from 5298 female sex workers, including 2530 street-based sex workers and 2768 venue-based sex workers from 10 provinces in Vietnam, were analyzed using descriptive statistics, bivariate and multivariate logistic regression analyses. HIV prevalence among the overall FSW population was 8.6% (n = 453). However, when stratified by female sex worker subpopulations, HIV prevalen...

The formulation is based on two main curves of hysteresis that are identified experimentally. In the proposed model, an adjusting function that relates the outer curve and its next minor is given. Its coefficients are obtained from the boundary conditions and experiment. From this adjusting function, a recursive-based polynomial formula for the cases of monotonic increasing and decreasing of input excitation are developed to predict the hysteresis. To evaluate the accuracy of the proposed new model, experiments with two different waveforms are carried out.

The injection-locked Fabry-Perot laser diode is used as low-cost colorless transmitters for high-speed optical access exploiting wavelength-division-multiplexing technology. The modification of main characteristics of Fabry-Perot laser such as spectral properties, noise and modulation is shown in injection-locking regime. The strong dependence of these properties onto injection parameters is also given. Finally, the operation of injection-locked Fabry-Perot laser diode in a wavelength-division-multiplexed optical access system using a novel multi-wavelength master source based on quantum-dash mode-locked laser is presented and its transmission performances at 2.5 Gb/s are reported.
